<?php // Example of filtering an array in PHP // Using array_filter to filter out values based on a condition $array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; // Remove even numbers $filteredArray = array_filter($array, function($value) { return $value % 2 !== 0; // condition: keep only odd numbers }); print_r($filteredArray); // Output: [1, 3, 5, 7, 9] ?>
